5 claims. (c1. .24a-,6st I This invention relates to holders for supporting paper rolls in paper machines or machines utilizing paper web, such, for example, as printing presses, and the object is to provide a simple arrangement of holder permitting rapid change of the rolls.

My invention will be well'understood in view of the following description taken in connection with the accompanying drawing, wherein:-

Fig. 1 is a broken elevation of a holder, a roll being indicated in dotted lines; f

Figs. 2 and 3 are enlargedl verticalV sections showing portions of the holder in different positions; and

Fig. 4 is a detail of certain ofthe parts in elevation.

Referring to Fig. 1 of( the drawing, I have there shown a roll-supporting shaft 1 carried rotatably on standards 9 and on which the roll R is carried to revolve therewith by means engaging the core or the central opening of the roll. This engaging means may take the form of cones I I and I3 strung on the shaft 1 and adapted to enter the core of the roll from opposite ends. Herein I have shown a cone II at the left which for purposes of the present description may be considered as fixed on the shaft. The cone I3 at the right is adapted tol be withdrawn over the end of the shaft to provide for the release of the roll and is clamped in adjusted position relative to the cone I to suspend the roll R between them. Herein cone I3 is held pressed toward the left by means of an abutment which interlocks with a threaded portion I5 on the shaft.

The abutment shown is formed of two separable parts, one comprising a sleeve or annulus I'I loosely embracing the shaft and presenting at its inner surface a segmental threaded portion I9 which in the form of the invention shown is for convenience in manufacture a separate piece secured within the sleeve by screw 2|. Due to the loose fit of Sleeve I'I about the shaft, the segment may either be moved laterally out of mesh with the thread I5, as indicated in Fig. 3, or moved up into mesh therewith as in Fig. 2. The parts I'I and I9 thus might be considered as a nut having a portion of its thread cut away to permit the shaft to move laterally as described in the opening in the sleeve opposing segment I9. The cooperating portion of the abutment may comprise a sleeve 23 slidable over the shaft, which sleeve carries projecting therefrom a segmental portion 25 complementary in circumferential eX- tent to the segment I9 but adapted to move over the crests of the threads I5 on the shaft.

Assuming lthe parts to be in the position. of Fig. 3 with the segment I9 out of mesh, to secure the' cone I3 in vadjusted position within the 'end of the roll as in Fig.. 2 the sleeve' I'I maybe slid. 1

up'against the end Vof the, cone. and then moved t5'I laterally to mesh the segment t9 with the thread on the shaft. To hold itin this positionsleeve 23 is slid along the shaft so thatv the segment 25 enters within the hollow of the sleeve' Il to mate with the segment t9. s1eeve Iris thus sup- 10 ported substantially centrally of theshaft and the segmentl I9 is maintained in mesh. If now a relative rotation between segment I9 and the shaft is effected as by manually turning sleeve 23 to drive threaded segment I9 through the mating segment 25, the reaction of screw threads I5y tending to burst the nut which isengaged therewith causes segment I9 to climb outwardly along the threads and thus to expand the mating segments I9 and 25 against the interior face of 20 the sleeve II, clamping the parts securely in position and holding the cone in the position of Fig. 2. If it is desired to release the roll a fraction of a turn will release this clamping engagement permitting the sleeve 23 to be drawn to the right, 25

withdrawing segment 25 and permitting sleeve I1 to drop or be moved laterally to unmesh it from the threads I5 on the shaft. While the organization of the segments on sleeves as here described maintains them on the shaft and prevents them from dropping free, it is clear that after this release both sleeves and the cone I3 may be merely slid off over the end of the shaft,

thus providing for a release of the roll and its 35 withdrawal in a very quick manner.

I am aware that the invention may be embodied in other specic forms without departing from the spirit or essential attributes thereof, and

I therefore desire the presentfembodiment to be 40 considered in all respects as illustrative and not restrictive; reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

I claim:

1. A roll holder for supporting paper rolls in printing machines and the like comprising a rotary shaft having an abutment secured thereon to engage within one end of the roll, the shaft being threaded adjacent the other end, and an 50 abutment slidable over the shaft to engage the other end of the roll, and means to secure the latter abutment in position comprising a sleeve loosely embracing the threaded shaft and carrying a segmental nut and a second sleeve slid- 5 able along the shaft having a segmental projection to enter the first named sleeve tor mesh the nut with the thread of the shaft.

2.. A roll holder for supporting paper rolls in printing machines and the like comprising a rotary shaft having an abutment secured thereon to engage Within one end of the roll, the shaft being threaded adjacent the other end, and an abutment slidable over the shaft to engage the other end of the roll, and means to secure vthe latter abutment in position comprising a threaded segment and a plain segment, sleeves supporting said segments on the shaft and Within one of which the segments When mated may be received with the former meshed With the thread of the shaft, the sleeve supporting thev threaded segment having an opening permitting unmeshing,v laterallyr of the segment from the thread of the shaft.

3. A roll holder for supporting paper rolls in printing machines and the like comprising a rotary shaft having anl abutment secured thereon to-engage Within one end of the roll, the shaft being threaded adjacent the other end, and an abutment slidable-over the shaft to engage the other end'ofV the roll, and means to secure the latter abutment in position Comprising complementary threaded and unthreaded segments, an annulus receiving said segments to position the same on the shaft as a split, segmentally threadfed nut, the parts being supported from the shaft with provision for relative longitudinal movement of the segments along the shaft and lateral unmeshing movement of the threaded segment when longitudinally separated from the un- ,threaded segment.

4. A roll holder vfor supporting paper rolls in tary shaft having an abutment secured thereon to engage Within one end of the roll, the shaft being threaded adjacent the other end, and an abutment slidable over the shaft to engage the other end of the roll, and means to secure the latter abutment in position comprising a nut cut away at its inner circumference to permit it to be laterally disengaged from the thread of the shaft and a key slidable axially along the shaft into said out away portion substantially to fill i the same to hold the nut in mesh.

5. A roll holder for supporting paper rolls in printingV machines and the like comprising a rotary shaft having an abutment secured thereon to engage Within one end of the roll, the shaft being threaded adjacent the other end, and an abutment slidable over the shaft to engage the other end of the roll, and means to secure the latter abutment in position comprising a segmental threaded member in itself adaptable to be moved laterally into and out from mesh with the thread on the shaft, a member mating there- With and a member for encircling both the threaded member and the mating member, the mating member and the encircling member being telescopically movable lengthwise of the shaft and, when assembled with said segmental threaded member, With the mating member in opposition thereto and the encircling member encircling both the segmental threaded member and the mating member, serving to hold the former in mesh With the thread of the shaft and then also serving when the threaded segment is turned relatively to the shaft to hold the threaded segment clamped on the shaft.
